- The polled position is also the composite-blend position: at 16 ms a 240 fps session reused a stale position for ~4 consecutive frames and the composited pointer visibly stuttered against the video. 4 ms out-paces every session rate; a tick is one GetCursorInfo syscall. - Log the queried DISPLAYCONFIG_SDR_WHITE_LEVEL scale on each blend- scratch rebuild so an HDR session shows what is actually applied (the virtual display's own SDR-brightness setting is the suspect when the cursor still reads dark).
